Installation

Copy the "scale" folder into the following folder: {moodle root}/question/type

Log in as administrator and load the "Notifications" page on the Moodle home page - this will create database tables used by the question type

Within a quiz, select "Scale" in the "Create new question" dropdown menu

Troubleshooting

Failed to load question options from the table question_scale for questionid xxx: The likely cause for this error is that a required database table is missing. To correct the issue, load the "Notifications" page on the Moodle home page (located just under "Site Administration", while logged in as administrator). Please note that any question created before fixing this issue will have to be discarded.
